	I initialized as follows:

	       internal static FontFamily fontArial = new FontFamily("Arial");

	      internal static PdfTrueTypeFont font9 = new PdfTrueTypeFont(new Font(fontArial, 9), 9, true);        

	

		        var textBox = new PdfTextBoxField(page, resourceKey);
	

		        
	

		        textBox.Bounds = textBoxRect; // already defined
	

		        textBox.Font = font9;
	

		        textBox.Password = false;
	

		        textBox.Multiline = false;
	

		        textBox.ForeColor = new PdfColor(Color.Black);
	

		        textBox.BorderWidth = 0;
	

		        textBox.DisableAutoFormat = true;
	

		        textBox.MappingName = resourceKey;
	

		        doc.Form.Fields.Add(textBox);


	The form field shows up in the document without issue, However, if I try to enter a non alphanumeric ASCII character - like "@" it just enteres a few spaces in the generated textbox field on the final pdf. 

	And if I try to enter a unicode char into the field, like "è" or "à", the pdf does not allow the char to be entered, even though the font is set up to work for unicode (and will work with unicode if I do a regular DrawString() call using the font).

	If I initialize the font like this

	        internal static PdfTrueTypeFont font9 = new PdfTrueTypeFont(new Font(fontArial, 9), 9, false);

	 

	 

	and this indicate that it is not for unicode, then the non-alphanumeric ASCII char (@) can be entered. Unicode chars still cannot be entered.

	 

	My expectations

	

		Any ASCII chars, including non-alphanumeric chars, like @ should always be enterable into any textbox field, regardless of font
	

		Unicode chars should be enterable if the font has unicode turned on


	Am I doing something wrong? Or is this a bug?

	I am fairly sure that this is an issue with your implementation, since I have never had an issue entering either non-alphanumeric ASCII chars nor Unicode chars into pdf files created with Acrobat.
